Description

Technical Field

[0001] This utility model belongs to the field of automotive door lock buffer technology, specifically a new energy vehicle door lock buffer mechanism. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles. Car door locks are one of the important components of new energy vehicles.

[0003] A car door lock buffer mechanism is an integral part of a car door lock, designed to cushion and protect the car door frame and door. In existing technology, Chinese patent CN219993428U discloses a car door lock buffer mechanism including a car door frame, a bolt, and a buffer unit. The car door frame has a mounting groove, the bolt is mounted on the car door frame and located on one side of the mounting groove, and the buffer unit is mounted in the mounting groove and located on one side of the bolt. The buffer unit includes a buffer element, a compression element, and a limiting element. The compression element is mounted in the mounting groove with its compressed end facing the bolt. The buffer element is mounted on the end of the compression element near the bolt, with a portion of the buffer element passing through the mounting groove and extending outside the groove. The limiting element is mounted in the mounting groove of the car door frame and connected to the buffer element. In this car door lock buffer mechanism, when the buffer element is compressed, the compression element compresses; during movement, the limiting element limits the buffer element, effectively preventing the buffer element from contacting and colliding with the car door frame during movement, thus protecting the car door frame.

[0004] However, the car door lock buffer mechanism provided in the above technical solution still has many shortcomings in actual use. For example, the buffer and shock absorption are achieved by the elasticity of the spring. After long-term use, the spring is prone to deformation, which weakens the elasticity and affects the shock absorption effect, resulting in poor practicality. Utility Model Content

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0026] Please see Figure 1 and Figure 2This utility model provides an embodiment of a new energy vehicle door lock buffer mechanism, including a car door frame 1. A buffer groove 2 is provided on one side of the car door frame 1, and a bolt 3 is provided on one side of the buffer groove 2. Both ends of the bolt 3 are threadedly connected to mounting rings 12. Multiple fixing bolts 13 are threadedly connected to the outer side of the mounting rings 12. The fixing bolts 13 pass through the mounting rings 12 and are threadedly connected to the car door frame 1. The fixing bolts 13 are evenly distributed in a ring about the central axis of the mounting rings 12. By setting the bolt 3 and cooperating with the components on the car door frame 1, the car door can be locked. Loosening the fixing bolts 13 and using the mounting rings 12 allows the bolt 3 to be disassembled and replaced.

[0027] Please see Figure 3-5 In this embodiment, a first magnet 4 is fixedly connected to the bottom of the buffer groove 2. Telescopic rods 5 are fixedly connected to the four corners of the first magnet 4. A second magnet 6 is fixedly connected to the end of each telescopic rod 5. The polarity of the opposite surfaces of the second magnet 6 and the first magnet 4 are the same. A pad 7 is fixedly connected to the side of the second magnet 6 away from the telescopic rod 5. The second magnet 6 is parallel to the first magnet 4. The outer dimension of the pad 7 matches the inner dimension of the opening of the buffer groove 2. One side of the pad 7 is in contact with one side of the second magnet 6. Through the repulsive force between the first magnet 4 and the second magnet 6, combined with the use of the telescopic rod 5 and the pad 7, a buffering effect can be achieved when the car door is closed, thereby protecting the car door frame 1. Furthermore, the parallelism of the first magnet 4 and the second magnet 6 ensures uniform repulsive force, thus improving the buffering and shock absorption effect. Moreover, the magnetic force of the magnet is more stable than the elastic force of a spring, ensuring stable shock absorption over long-term use and enhancing the practicality of the device.

[0028] Please see Figure 1 and Figure 5 In this embodiment, the four sides of the gasket 7 are fixedly connected with flexible inclined edges 8, and the other end of the inclined edges 8 is fixedly connected to the car door frame 1. The opening of the buffer groove 2 is sealed by the gasket 7 and the inclined edges 8. Through the cooperation of the gasket 7 and the inclined edges 8, the buffer groove 2 can be sealed, thereby protecting the internal components of the buffer groove 2 and preventing external dust particles from entering the buffer groove 2. At the same time, the flexible material of the inclined edges 8 does not easily affect the movement of the gasket 7.

[0029] Please see Figure 5In this embodiment, the telescopic rod 5 is symmetrical about the center line of the first magnet piece 4. The second magnet piece 6 is fixedly connected to a crossbar 9 on the side near the telescopic rod 5, and the horizontal center line of the second magnet piece 6 coincides with the horizontal center line of the crossbar 9. The telescopic rod 5 is located at the four corners of the second magnet piece 6, and the crossbar 9 is provided in the middle of the second magnet piece 6, which can enhance the stability of the support for the second magnet piece 6. By using the cooperation of the sliding groove 11 and the sliding piece 10, the stability of the movement of the second magnet piece 6 can be guaranteed, and the deformation of the second magnet piece 6 can be prevented.

[0030] Please see Figure 3-5 In this embodiment, both ends of the crossbar 9 are fixedly connected to sliders 10, and both sides of the buffer groove 2 are provided with sliding grooves 11. The sliding grooves 11 are symmetrical about the center line of the buffer groove 2. The sliding grooves 11 and the sliders 10 are slidably connected. The outer side of the sliders 10 is in contact with the inner wall of the sliding grooves 11. The sliders 10 are symmetrical about the center of the crossbar 9. By using the sliding grooves 11 and the sliders 10 together, the stability of the movement of the second magnet 6 can be guaranteed.

[0031] Working Principle: When using this device, the locking bolt 3, in conjunction with the components on the car door frame 1, can lock the car door. Loosening the fixing bolt 13, and using the mounting ring 12, allows the locking bolt 3 to be disassembled and replaced. The repulsive force between the first magnet 4 and the second magnet 6, combined with the telescopic rod 5 and the washer 7, provides a buffer when the car door closes, thus protecting the car door frame 1. Furthermore, the parallelism of the first magnet 4 and the second magnet 6 ensures that the repulsive force between them... The uniform repulsive force enhances the cushioning and shock absorption effect. The telescopic rod 5 is located at the four corners of the second magnet plate 6, and a crossbar 9 is provided in the middle of the second magnet plate 6 to enhance the stability of the support for the second magnet plate 6. The cooperation of the sliding groove 11 and the sliding piece 10 ensures the stability of the movement of the second magnet plate 6. The cooperation of the gasket 7 and the inclined edge 8 can seal the buffer groove 2, thereby protecting the internal components of the buffer groove 2 and preventing external dust particles from entering the buffer groove 2. At the same time, the flexible material of the inclined edge 8 does not easily affect the movement of the gasket 7.

[0032] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
